Abstract: A footstep guide rail (3) (rail body 3a) is arranged so that a level H of a horizontal surface is set at the position obtained by adding a designated offset ? to a tangential line L of a drive sprocket (9) and the footstep guide rail (3) is provided, at its one end on an introductory side of the drive sprocket (9), with a curved part (13). At a reference position closest to the drive sprocket (9), the horizontal surface of the footstep guide rail (3) is changed to the curved part (13). Consequently, it is possible to absorb velocity unevenness of one footstep roller approaching the drive sprocket (9).

Abstract: A conveyor apparatus is provided that is free of a pulsing motion in the circulating chains so as to provide a comfortable ride quality on its steps. The conveyor apparatus includes a step guide rail, a plurality of steps, a step chain, and a chain driving mechanism for driving the step chain. The chain driving mechanism includes a rotating and driving unit, a driving sprocket which is rotated by a driving force given by the rotating and driving unit, and a circulating chain for giving a thrust to the step chain. The circulating chain has chain links and hinges that are to be connected to the adjacent chain links. The chain link includes a placing surface on which the step roller is placed, and pressing surfaces that are in contact with step rollers.

Abstract: A mountainous or valley-shaped curved part 13 is provided in a part of a footstep guide rail 3 for guiding a movement of footstep rollers 5 linked by a footstep chain 7, the part being positioned in the vicinity of a drive sprocket 9. Consequently, owing to meshing of the footstep rollers 5 with the drive sprocket 9, an unevenness in velocity of the footstep rollers 5 is absorbed by the curved part 13, so that a moving velocity of the footstep rollers 5 moving on the downstream of the curved part 13 is maintained constantly, suppressing vibrating of the footsteps 4.

Abstract: There is provided a conveyor apparatus free of pulsing motion in circulating chains to provide a comfortable ride quality on steps. A conveyor apparatus 1 includes a step guide rail 3, a plurality of steps 5, a step chain 4, and a chain driving mechanism 10 for driving the step chain 4. The chain driving mechanism 10 includes a rotating and driving unit 11, a driving sprocket 12 which is rotated by a driving force given by the rotating and driving unit 11, and circulating chain 13 for giving a thrust to the step chain 4. The circulating chain 13 has chain links 13a and hinges 13b to be connected to the adjacent chain links 13a. The chain link 13a includes a placing surface 13c on which the step roller 4b is placed, and pressing surfaces 13d and 13d that are in contact with step rollers 4b.

Abstract: An exhaust system of a multi-cylinder engine of a motorcycle comprises exhaust pipes leading from the respective cylinders of the engine, the exhaust pipes are collected as a single exhaust pipe collection unit, a muffler to which the collection pipe section are connected, an interconnecting pipe through which the exhaust pipes and the muffler are connected, an exhaust control system for controlling pulsation of an exhaust gas, the exhaust control system including a valve mechanism disposed in operative association with the interconnecting pipe, a drive unit for operating the valve mechanism, and a central processing unit for controlling the drive unit.

Abstract: The oil cooler has four fastening sites for fastening bolts, two sites on each side of the oil cooler when viewed from the front. The exhaust pipes are arranged so that spacings between exhaust pipes are arranged at least in front of the center of the oil filter and in front of the inner fastening sites of the oil cooler, respectively.

Abstract: An overall cylindrical oil filter and oil cooler are arranged widthwise of the vehicle on the left and right and projected forwards, at the lower front part of the engine case of the engine. The oil filter is disposed offset to the right side of the vehicle's width or to the side opposite to the kickstand with respect to the vehicle's center line while the spacing between the exhaust pipes for #2 and #3 cylinders are arranged vertically below the oil filter when the bike is held with the kickstand set down to the ground.

Abstract: In an exhaust system for a motorcycle with a V-type engine mounted thereon, the front cylinder exhaust line has a first exhaust pipe arranged to the front while the rear cylinder exhaust line has a second exhaust pipe arranged to the rear. The first and second mufflers are attached to one side of the vehicle body with the second muffler arranged in parallel to and above the first muffler and shifted behind with respect to the first muffler. The first expansion chamber of the first muffler and the first expansion chamber of the second muffler are connected to be in communication with each other by means of a communicating pipe. One end of the communicating pipe is joined to the peripheral surface of the muffler cylinder corresponding to the first expansion chamber of the first muffler while the other end is connected in parallel with the second exhaust pipe to the front-end entrance port of the second muffler corresponding to the first expansion chamber of the second muffler.
